1. Market stall, containing a base, a table top and a roof, characterized in that it consists of base elements (1) and (2) having lengthwise axes lying in different parallel planes, supporting elements of the roof (11) and (12), structural elements of the roof (21) and (22), and distance elements (4), (5), (15) and (19), connected together detachably at nodes (A), (B), (C), (D), (E), (F), (G), (H) and forming two three-dimensional structural systems connected at nodes (B), (C), (D), (G), (H) by means of tubular bracing elements (3), (13), (14), (24), (23), while the base elements (1) and (2) crossing at node (B) connect on one side at nodes (C) and (D) to the outer elements of the table top (10), and on the other side near the ground at nodes (E) and (F) to the supporting elements of the roof (11) and (12) crossing at node (A), while at nodes (D) are fastened moving distance elements (15) and (19), and distance elements (4) coupled to the base elements (2) are fastened at nodes (C) and (B), and distance elements (5) are coupled to base elements (1) at nodes (B) and (D), whereas the table top consists of alternately arranged table elements (10) threaded onto bracings (13) and (14) and moving stand elements (20) threaded onto bracing (14) which is on the seller's side, while the upper sections of the supporting elements of the roof (11) and (12) connect to the structural elements of the roof (21) and (22) to form two nodes (G) and (H), where node (G), the highest above the ground, is also the point of connection of the structural elements of the roof (21) and (22).<IMAGE>
